CAR-DOOR FASTENING.

SPECIFICATION forming part of Letters Patent No. 223,705, dated January20, 1880. Application filed October 22, 1879. v

To all whom it may concern:

Be it known that we, W. H. BUSER and B. L. SHAW, of Denison, in thecounty of Grayson and State of Texas, have invented a new and valuableImprovement in Universal Car- Door Fastening and Uleat; and we do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being bad to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side view of a car,showing our improved fastener applied. Fig. 2 is a vertical sectionthereof, and Fig. 3 is a horizontal section of the same.

This invention has relation to improvements in fastenings for slidingcar-doors; and the nature of the invention consists in certain novelarrangements and constructions of the devices used, as will behereinafter more fully set forth.

In the annexed drawings, the letter A designates a car-door slidingedgewise in ways or guides at, and closing a doorway in'the side B ofthe car. WVhen fully open, the door abutsagainst a stop, a, or otherequivalent device, and is prevented thereby from being thrown out of itsways.

0 indicates a metallic box let into the side of the car so as to beflush therewith and not interfere-with the opening of the door. This boxhas in its face a deep L-shaped recess, of, one branch of which(lettered b) is horizontal .and the other (lettered 1)) vertical.

At the middle of the branch I) is a vertical bolt, 0, upon whichvibrates horizontally a vibrating block, D, having the shoulders c e,

and at its free end the rabbeted lugf, having a perforation, t.

The block D has free vertical movement from top to bottom of thevertical branch of the recess a and the reverse, and, being at the upperend of the said branch, may be swung back into the horizontal branch I).In

this position the outer face of part D, which may be called thestaple-block, is flush with the face of the box 0 and with the side ofthe car, so that the door slides past it without interference.

When the staple is swung out at right angles to theside of the car, thedoor being closed, the staple-block drops automatically to the bottom ofthe vertical branch of the recess ad, in which position the shoulders ee bear against the face of box 0 at each side of the said verticalbranch, and the rabbeted lug f extends out sufficiently beyond the outerface of the door to receive a staple, E, fixed thereto.

It will be observed that the body 9 of the staple'block bears againstthe edge of the door, and, being of a size to fit nicely in the bottomof branch I), cannot vibrate or play. Consequently it opposes aninsuperablc obstacle to the opening of the door.

The hasp is secured to the staple-block by means of a padlock, andprevents the said block from being raised and swung into the horizontalbranch of the recess.

' I When the stapleblock is in the horizontal branch of the recess a itis locked therein by means of swing-button Gr, pivoted at l to the box 0and arranged in aseot-orshaped recess, j, in its face. This button maybe swung upward on its pivot l to admit the block 1), and downwardlyafter its admission to confine it. The parts of our improved fastenenareall of metal, either cast or wrought, or part may.

be cast-as, for instance, the box G-and the balance wrought.

What we claim as new, and desire to secure by Letters Patent, is-- 1. Ina sliding-door fastening, the combination, with the car B and slidingdoor A, of the box 0, having the L-shaped recess a the rod 0 in thevertical branch of said recess, and the vertically-movablehorizontally-vibrating staple-block D, having the staple-eyefifadaptedto be engaged with a hasp on the door, substantially as specified.

2. The combination, with the car B and its sliding door A, of the box 0,having the L- a shaped recess a and the shallow sector-shaped recess j,the rod 0 in the vertical branch of recess a the staple-block D, havinga vertical and horizontally-vibrating movement on said rod, and theswing-button G, vibrating in recess j and lockin g the block D in andreleasing it from the horizontal branch of recess a substantially as setforth.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
